GRAFTING OF PLANTS IN THE SYSTEM OF MEASURES FOR GROWING OF THE CUCURBITACEAE FAMILY
Abstract
Despite its ancient history, in modern conditions grafting is a technology that is not only widely used, but also constantly improved. Its application in the system of activities for growing plants of the Cucurbitaceae family is an integral part of solving one of the priority problems of humanity: providing the population with food products. The purpose of this publication is a review of literary sources devoted to the issue of the use of this technology in the cultivation of plants of the Cucurbitaceae family. At the same time, pumpkins are widely used as rootstock. When evaluating the effectiveness of the application of the specified technology, considerable attention is paid to the study of yield indicators and plant productivity. It has been shown that grafting can really achieve early harvesting, extend the growth period and increase yield. At the background of grafting, there is often a change in the quality of the received fruits (their shape, skin thickness, juice pH, glucose, amino acid, mineral elements, etc.). For the most part, it is noted that the changes registered in fruits when using vaccination are not accompanied by a fundamental deterioration in the quality of the obtained products. At the same time, literary sources note that an unsuccessful combination of plants selected for grafting can lead to a decrease in both yield and product quality. That is, the selection of an appropriate combination of rootstock and scion is the key to achieving high productivity of melon crops. The facts recorded in grafted cultures regarding yield indicators, growth rate, fruit characteristics, etc. are a natural result of physiological changes that occur during the cultivation of such plants. As a result of grafting, in particular, the plants showed changes in the absorption of water and mineral elements, synthesis of phytohormones, activation of the flow of substances and energy exchange, and increased cold resistance of plants. Grafting is also a means of influencing the eco-characteristics of individuals and modeling plants with traits that meet production requirements. In particular, the use of grafting is effective in solving the issue of increasing salt tolerance of members of the Cucurbitaceae family. The results of many studies prove that grafting, including through the use of highly resistant or immune rootstocks, can significantly improve the resistance of plants to diseases. In turn, grafted plants in a disease-free environment showed higher yields, average fruit weight, soluble dry matter content, and plant survival.
